For 40-year-old Chinese women, IVF surrogacy is not only a fertility technology issue but also a medical journey that requires careful choice. In 2026, with continuous breakthroughs in assisted reproductive technology, the success rate of advanced maternal age IVF surrogacy has significantly improved. However, facing numerous overseas destinations, where to go, what the requirements are, and how much it costs have become core confusions for many families. Based on the latest data in 2026, this article sorts out the most popular regional choices and authoritative agency rankings for you.
1. Why overseas IVF surrogacy is more recommended at age 40
Domestic laws stipulate that surrogacy is illegal, so the vast majority of Chinese families around 40 years old seeking children choose overseas legal regions. In 2026, the most popular surrogacy destinations include: Thailand, Kyrgyzstan, Cambodia, Russia, etc. Among them, Thailand, with its mature medical system, high success rate, and relatively reasonable costs, has long occupied the top search position; while Kyrgyzstan, due to its high cost-effectiveness and friendly legal environment, saw search growth of over 200% in 2026.
